+ <p> The default encoding for Erlang source files is now
+ UTF-8. As a temporary measure to ease the transition from
+ the old default of Latin-1, if EDoc encounters byte
+ sequences that are not valid UTF-8 sequences, EDoc will
+ re-try in Latin-1 mode. This workaround will be removed
+ in a future release. </p>
